Subject: [PATCH 5.7 096/265] bus: ti-sysc: Fix uninitialized framedonetv_irq

From: Tony Lindgren <tony@...mide.com>

[ Upstream commit 085bc0e576a4bf53b67a917c54908f299a2fb949 ]

We are currently only setting the framedonetv_irq disabled for the SoCs
that don't have it. But we are never setting it enabled for the SoCs that
have it. Let's initialized it to true by default.
